## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

AT CRUISE ALTITIUDE, 1500 MSL, 31 MANIFOLD PRESSURE AT 2300 RPM, THE PILOT NOTICED HEAVY VIBRATION ON THE LEFT ENGINE FOR 10 TO 15 SECONDS. THE LEFT ENGINE WAS SHUT DOWN AND THE AIRCRAFT RETURNED TO DEPARTING AIRPORT WITHOUT FURTHER INCIDENT. PRELIMINARY INSPECTION REVEALED THE ENGINE CASE WAS DAMAGED, INCLUDING SEVERAL BROKEN PISTON ROD END BOLTS. THE AIR CARRIER SENT THE DAMAGED ENGINE TO A CERTIFIED REPAIR STATION FOR ENGINE TEARDOWN AND REPAIRS.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
